By using- figures in the place of writing or printing the names in 

 full, much unnecessary space can be dispensed with ; and thus a plan 

 of a locality on the scale of three or four inches to the mile, might 

 be conveniently introduced into a duodecimo or octavo volume. Any 

 additional localities the botanist might discover could with facility be 

 marked on the spot in their proper situations, by making additional 

 figures on the plan, which figures of course to agree with the names 

 of the plants upon a separate page. In this way it appears to me 

 that much time might be spared the naturalist for his other pursuits, 

 and also be the means of producing more complete and accurate local 

 Floras than any plan hitherto adopted. 



In conclusion, I have a few remarks to make upon the dispersion 

 of species in the environs of London. The former hints respecting 

 the eradication of plants will be sufificient to those collectors who are 

 in the habit of Tierhalizing into various counties. Such individuals 

 must bear in mind, that the lover of natural history is the more or 

 less proud of his country, according to the specimens of interest and 

 value that have been collected in it. Take for instance the 

 county of Surrey — what would it be to the botanist without its orchi- 

 deous and chalk plants, for which it has been long celebrated. At 

 Boxhill, and the hills adjoining, with other places in the neighbour- 

 hood, (and in this, as well as all places hereafter cited, within a dis- 

 tance of thirty miles of London,) the following lists of orchideous and 

 other uncommon plants have been found.
